Welcome to the World of AgentC Marketing!

AgentC Marketing works with marketing companies and businesses to make brands synonymous with their industries.

You probably know me as

Sara Tyberg

brand strategy

To me, brand strategy and marketing is all about peeling away layers to get to the core.

I work with companies who rely on thought-out verbiage and careful explanations. Over the years, I’ve developed a reputation for clarity and strategy. One of my most useful tricks is taking a step back and seeing the full picture.

Formerly The Document Docs, AgentC Marketing gives you perspective on your company and translates concepts into tangible words.

What is

AgentC Marketing?


There’s no hidden agenda other than the problem you need solved. Your voice is the only one coming through; a point especially important for marketing companies.

AgentC Marketing is a dedicated copy + strategy agent working on your behalf.

AgentC Marketing


C is for copy, the core of everything done here. I’m the word person, itching to translate your message into words that will resonate with anyone reading it.

When the wording is clear, professional, on vibe, and punchy, you’re going to attract customers.

AgentC Marketing


Before diagnosing and creating a strategy, I analyze all components. My years of experience in collaborating with top creatives gives me a broad scope of effective marketing methods.

Take your company

closer to its goal!

PolyMaven brand book

Whether your brand is new or established, you may need to re-examine it from time to time. Sometimes it’s a slight tweak to your mission and goals, and sometimes it’s a thought-out plan covering all angles. Find your brand at the point where your company’s core meets your audience’s pain points. Walk away with a robust document that outlines a guide for your brand, both internal and external. Get clear direction for creating deliverables in line with your brand, so your messaging is consistent.

I have had the pleasure of working with various copywriters, but none come close to Sara’s incredible talent. The way she crafts sentences and ideas is nothing short of impressive. Her ability to identify the core issues and extract valuable insights is remarkable. Her thought-provoking questions have led us to explore new perspectives and discover hidden opportunities, contributing significantly to our success.

Nice to meet you

We discuss the basics to make sure I’m the right person for your project. We sign a contract with clear terms to avoid miscommunication, and set a start date.


A world to discover

We get on a Discovery call with a prepared list of questions related to your specific deliverable and industry. You leave the call with clarity on upcoming steps.


Research! Copy! Action!

The gears begin moving as I start working on your project, including research, site map, brand summary, surveys for your customers, and more. At the end of the predetermined time, your copy is ready for review!


Wrapping up a good thing

Now’s the time for the live or recorded presentation. You get a chance to review and request revisions. If applicable, your project will proceed to design and/or development. If this is where our contract ends, I’ll collaborate with your design/dev team and fill in missing pieces as they come up.
